Design of the de Havilland DHC-2
Beaver light transport was started in Toronto during late 1946. The concept behind this first of de Havilland Canada's line of effective STOL transports was influenced by the specific requirements of the Ontario Department of Lands and Forests. The resulting aircraft also suited the exacting requirements of 'bush' pilots in North America and elsewhere for an effective, rugged and reliable STOL utility transport.
The prototype was flown for the first time on 16 August 1947, and the type was certificated in Canada during March 1948. Large-scale production had already begun, and the Beaver I was soon in service, powered by the Pratt & Whitney R-985 radial. Of the 1,657 Beaver Is built, no fewer than 980 went to the US forces (YL-20 service test, L-20A and L-20B production aircraft, redesignated U-6 in 1962) and 46 to the British Army. There followed a single Beaver II with the Alvis Leonides radial and, in 1964, a few 10-passenger Turbo-Beaver III powered by the 431kW United Aircraft of Canada Ltd (later Pratt & Whitney Aircraft of Canada) PT6A-6 or -20 turboprop. Most of the Turbo-Beavers were used by civil operators. In New Zealand one Beaver had an AiResearch TPE331 turboprop engine installed. Production ended in the mid-1960s as de Havilland Canada concentrated on the development of more ambitious projects and products.
At the height of its career, the Beaver was to be found in some 50 countries, where it won universal acclaim for performance, ground stability conferred by wide-track tailwheel landing gear, and versatility. Basic accommodation was provided for a pilot and seven passengers, the latter replaceable by up to 680kg of freight. Great flexibility was bestowed on the Beaver by its ability to operate on wheel, ski, float or amphibious float landing gears.
Airtech Canada of Peterborough, Ontario, has converted a number of Beavers to take the 447kW Polish PZL-3S seven-cylinder air-cooled radial piston engine driving a PZL four-bladed propeller.

Hello. Give answer to the question please. Where to find detailed drawings of the Beaver??

I have been flying A Beaver commercially on the BC coast for 25 years. Although the practice is now rightfully frowned upon, I can verify from personnal experience that it can be flown off the water with water over the top of the floats almost to the rear spredder bar. I have taken off on floats with 25 kt+ 90 degree xwinds. And done a lot of things the Beaver is not supposed to do.

I flew "Beavers" in Vietnam from 1968-70 as a log support bird for Birddog companies. It was a great plane to fly out of 800 ft. dirt strips.

I've only seen a Beaver in the Canadian national air museum in Ottawa, but I do have a story from a pilot who flew them. I met Bud Voss, now deceased, through model airplanes. He bought a kit from me of the 8-foot span model made by Unionville Hobby of Markham, Ontario. Bud told me that as part of their military training they had to "land" a Beaver in a minimal distance. He did it in 13 feet! It was essentially a crash landing and the plane had to be rebuilt afterward, but that was standard procedure as part of their training.
Anyway, that's what he told me and there is no way to question him about it. He had no reason to lie about it.

To Bob Pedigo comment...18.09.2010. No wonder you didn't like the 20k xwind component you were working with. I remember the Beaver as having a 10k xwind component, and at times wished it were rated at 20 or even 30. That plane had a way of making you look good in the worst of conditions.
I am grateful to have had so many hours in it.

Ontario Ministry of Natural Resources bought registration # 2 of the line as well as many others. This Beaver was restored and to my knowledge still flies. It is equiped with Roll tanks for forest fire suppression mounted on the floats. While the original beaver was before my time with MNR it was a pleasure to hear many good stories from thos old firefighter about this fantastic aircraft.

I flew a Beaver on floats to Anchorage with a friend that owned it, he signed off my rating and I flew his other airplane back to Seattle. Nothing better then a round engine and like the 185 if you could get it in it would fly.

I flew Beavers in Borneo from 1964 to 1967 and I do not remember Barrie Davies. I flew with 130 flt RCT. Who else flew Beavers? Just very curious. It is always intriguing to find out what you missed. Please let me know. I totally agree with his assessment of the Beaver. She picked me up when I had a fuel problem and took me home. She flew on limited panel when things were really traumatic and you knew she would always respond.My boss Major John Riggall,now, I believe, became Lt Col John Riggall must remember that. I left the Army and went into civil flying, and for the last 18 years of them as a Captain with BOAC/British Airways. I will never forget that beautiful Beaver that was part of you. You thought it to do and it did. The VC10 and the Tristar were so similar. Barry Courtney.

|Mike Anderson, ekim50=ymail.com, 06.04.2011|
I retied from the USAF. Never flew or even sat on this plane. I sure wished I could have. Spent many hours being flown across Europe on most every plane we had there. But I wished it could have been on this one. It looks so great - what a plane should look like.

Beavers arrived in Ghane in packing cases in 1960 and we RAF men on secondment to the Ghana Air Force built them up in no time. Flying under the bridge on the Volta River was good fun.

I worked (crewchief)on a L-20 Beaver when I was in Germany fron 1959 to 1961. I was stationed with the 30th Transportation Co. at Fleigerhorst Kaserne in Langendiebach, outside of Hanau. The last three numbers were 921. Anybody know what happened to that aircraft? It was a great plane. I still have the P/W medallion from the oil tank. They went fast! Love to hear from someone who knows.

Flew the L-20 in Japan,Korea, USA,Libya, Colombia, and Iran Agreat AC
|Roger Pile, f102jock=hotmail.com, 05.03.2011|
Flew the L-20 at Scott AFB with the 85th FIS from 56-59. We used for parts pick-up and personnel movement. In 1970-71, got recurrent in it (now called the U-6) at Luke AFB where it was used to transport fighter pilots to the gunnery ranges as safety monitors, landing at unattended airstrips in the desert. Flew one of them to the boneyard at Davis-Monthan AFB on its last flight. Have fond memories of my hours in the Beaver, despite being primarily an F86D, F101B and F102 pilot.

I worked at de Havilland Canada. Put in over 20 years at the plant. Started in 1952 Lancaster Overhaul,onto Beavers then Otters. Left DH for a number of years to return to work on Dash-7, Buffalo and last group of Twin Otters and on to the Dash-8. Heard many stories from operators about Beavers, Otters and Twin Otters and what they were capable of doing. Beaver truly deserves the credit it gets for doing what most planes only hope they can do. The only plane that can replace the Beaver is another Beaver. The Viking Twin Otter is doing that now so it's time to replace the Beaver. At the annual "Wings and Wheels" at the old DH plant many a highly modified and up-dated Beaver worth into the seven figures all of 60+ years old gets admiring glances. Not bad for an old work horse that was considered too expensive at the time of it's introduction selling at $24,000.00. After starring in a movie featuring a Beaver Harrison Ford went and bought one and flies it regularly. There are many stories I heard of the Beaver's capability but the best one I remember of a Northern operator showing me a photo of a heavily loaded Beaver on floats sitting in the water level to the top of the rear of the floats. I enquired if that was risky? His reply was." That if it still floats its safe to take off". There is a pride at de Havilland to build the best product possible and even now as in the Bombardier family the tradition still goes on.

Hello my company have 05 DHC-2 with R-985 Engines we are facing lots of problem regarding the spares like fuel content gauges, fuel content Tx and Tech Generators because of there 5year life can you help me in this matter. We are also interested to convert our these aircraft in to Tube Beaver can we do this?

I flew the Beaver in 'Nam '69-'70 123rd Avn Bn - ChuLai and FRG - Frankfurt '70 - seperation racking up a bit over 1,100 hours in it. I loved the bird and wish I had been privy to the end of war auctions. Went to Alaska a few years back and was happy to see all the U-6's flying in that neck of the woods.
Do you have any comments about this aircraft ?
